摘　　要：探讨三色渐变圈圈纱的设计和纺制要点。概述了渐变圈圈纱的结构和生产原理，对影响外观效应的颜色、超喂比、捻度、芯纱张力和牵伸倍数进行了分析设计。合理选择了芯纱、饰纱和固纱原料，测试了纤维性能。纺制三色渐变圈圈纱时，双芯纱须从前胶辊的凹槽中通过，芯纱、饰纱、固纱要在空心锭下方的加捻钩上绕1圈～2圈，同时要保证渐变自然，从而顺利纺制出三色渐变圈圈纱，成纱外观良好，条干均匀，疵点少，圈圈大小分布均匀。认为：正确掌握成纱特点和纺纱工艺技术有助于花式纱线的开发。Design and key points of producing three-color gradient loop yarn were discussed. The structure and production principles of gradient coloring loop yarn were summarized. The yarn appearance influencing factors were analyzed and designed like color, overfeed ratio, twist, tension of core yarn and draft multiple. The raw mate rials of core yarn, decorative yarn and hinder yarn were chose rationally. The properties of fiber were tested. Doub- le core yarn got through groove on front top roller when three-color gradient loop yarn were prepared. Core yarn, decorative yarn and binder yarn were winded on twisting hook under hollow spindle for one to two circles. At the same time the gradients should have a natural feel, then three-color gradient loop yarn were spun successfully. The final yarns had a better appearance and evenness,less defects, and uniform distribution loops. It is considered that correctly grasping the spinning properties and techniques will be helpful to develop the fancy yarns.
